The chipper has unique features and innovations for biomass processing.
These new functions and devices have not been available on the market till now. The new chipper is characterized by a compact frame to allow manoeuvrability in constrained spaces. The mobility is optimized by a four-wheel drive system with three possible steering ways: each axle singly, both axles combined, or only the front axle. The narrow design is aimed at easy use in areas such as narrow roadways and reduced operation areas. The new model is also suitable for plantations and customers with spread biomass sources, such as orchards.
The low position of the feeding inlet improves productivity when processing small piles of material, such as the ones available in poplar forests and orchards; and for large piles of the biomass, such as is normally found on road sides. To allow bulky material to be processed, such as long branches, the lower feed roller has been changed with a longer feeding chain, which is able to transfer the material directly to the drum.
The drum has been designed to produce high quality chips, meeting the growing demand for modern high specification power stations, especially for gasification units. The drum has a diameter of 820 mm (32 in), a width of 1400 mm (55 in) and weighs 3500 kg (7700 lb). It is section-divided to better distribute the machine stress on the different components, reduce vibrations, noise and fuel consumption (which Pezzolato claims is 30% less than machines of comparable size).
The chip expulsion fan has continuous speed regulation to allow adjusting the speed to the real requirement, decreasing energy needs. The 400 kW (550 hp) turbo-charged Stage IV (euro 6) motor is equipped with EGR (exhaust emission blow-by) and SCR (Ad-Blue) systems to comply with emission standards, and avoids using a diesel particulate filter, which would reach too high temperatures during the regeneration to be assembled safely on a chipper when working in the dusty conditions created when processing dry wood biomass.
The wholly glazed cab is equipped with controls for total machine management, both for the machine movement and for the chipping, using a 12.1 inch touch-screen monitor. To broaden the area which can be reached by the crane and to improve the visibility of the area where the wood is loaded, the cab can be lifted and turned by 45 degrees. Source
